GEORGE W. RATHSAM, OF INDIANAPOLIS, INDIANA.

MACHINE FOR MAKING FLOWER-POTS.

SPECIFICATION forming part of Letters Patent No. 244,304, dated July 12, 1881. Application tiled May 3, 1881. (No model.)

To all whom t may concern:

Be it known that I, GEORGE WILLIAM RATHSAM, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Machines for Making Flower-Pots; and I do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertans to make and use the same, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to certain new and use-v ful improvements in machines for the manufacture of ilower-pots, and more especially to the class employing a revolving core-mold or male former, and a Inatrix or female former having a vertically-adj ustable bottom, the said core-mold and matrix being adapted to be brought together so as to form pottery articles within the space existing between the outer and inner surfaces of the said core-mold and matrix, and the newly-formed article lifted out of the matrix by said adjustable bottom; and myinventionhas for its object the production of a machine in which the matrix and adjustable bottom can be independently regulated or adjusted for the manufact-ure of differentsized pots; and theinvention consists in novel features of construction, and combination and arrangement of parts, all as will be herein fully described, and specifically pointed out in the claims.

Referring to the accompanying drawings, Figure 1 represents a side view of my improved machine; Fig. 2, a front view of the same; Fig. 3, a longitudinal section.

Similar letters of reference indicate like parts in all the views.

In the drawings, A represents the base, and B the four uprights of the frame of the machine.

C represents a frame adapted to be vertically adjusted, or moving in the slots b b of the front upriglits, B B, through the medium of the hand-lever D, fulcrumed in the upright D', and connected to the V-shaped lower end of said frame C by a cross-pin, d, working in slot d' in the front end of said hand-lever. The upper cross-piece, c, of the frame G is centrally provided with a ring, c', in which rests the exterior mold or matrix, E, secured therein by a setscrew, e.

F represents the interior core or former, adjust-ably secured on the lower end ot' the shaft G by a set-screw, f, said shaft workin g in bearings g g, and carrying at its upper end bevelwheel H, which meshes with a similar wheel, H', mounted on one end of a horizontal shaft, 7L, journaled in bearings h' h' on top of the frame of the machine, and carrying on its outer end a driving-belt wheel or pulley, I, through the medium of which wheels and pulley H, H', and I a revolving movement is communicated to said interior core or former, F.

J represents a crossbar, provided with slotted uprightsjj, connected to the front uprghts, B B, by set-screws z' i, and with said cross-bar J projecting pins or studs k, secured to the front sides of the side guides of the frame C,

engage for limiting the downward movement of said frame. The bottom of said exterior mold or matrix, E, is a circular plate or disk, II, having a punch, l, on its upper surface, and a downwardly-projectin g rod, l', connectedto its under side, which passes through a guide, m, and is provided with a screw-nut or stop, m', adjustable thereon, for limiting the downward movement of said plate or disk, in order to suit the proper height desired of pot to be lifted out of the matrix E. Y

The operation of my improved machine is as follows: Motion is communicated to the interior mold or core by the belt-wheel and gearwheels, as above described. Theinterior plate or disk, L, is then adjusted to suit the desired height of pot to be made, after which a sufficient Inass of clay or other material dipped in coal or other oil is placed in the matrix E. Then by pressing down on the hand-lever D the frame carrying` the matrix is raised, so that it will inclose the revolving core or mold which completes the operation of forming the pot, any surplus material being forced out over the edge of the exterior mold or matrix. The handlever being now raised, the frame and matrix will be lowered, leaving the formed pot on the bottom plate or disk, L,.or the pot adheres to the revolving mold and is taken off, the studs k on the frame C engaging the barJ at the proper IOO time to prevent a too far downward movement 3. In a machine for forming flower-pots, the of the matrix, and the bar J, being vertically combination,wi th an interior revolvingformer, adjustable, permits the matrix being limited of avertically-rnovableframe operated through 25 in its movement in accordance to the size of a hand-lever connected thereto, as shown, and
